Stability Seachem really works. Bacteria are in the spore stage until you put them in your tank, you have to wait for them to grow. After 2 weeks my ammonia levels stayed at 1ppm until the start of the 3rd week when I started seeing some nitrite. I've been using it for the last 7 days until my tank was completely tanked. Make sure you shake the bottle really well so the liquid looks milky, the spores are really hard to survive shipping when ordering.
